This is a set of instructions for building a physical model. The model simulates the Sun's paths across the sky at summer solstice, winter solstice, and the spring and fall equinoxes. A bead simulates the Sun, moving along a cord, from rising along...(View More) the eastern horizon to setting on the western. The bead can be moved from path to path to demonstrate solar alignments, the solstices, and equinoxes. The model is created to be unique to the user's latitude, and is useful for including in lessons that teach about the seasons or archaeoastronomy.(View Less)

This is an activity about Lunar samples. Learners will see snapshots of the Moon's history and hold an important artifact of American history with a Lunar Sample Disk. Earth rocks and soil of similar types as the lunar samples may be provided and...(View More) explored with hands, eyes, noses, and tools. Please note, checking out a Lunar Sample Disk requires training, a secure storage facility, and a minimum of a 6-week lead time. This activity is part of Explore! Marvel Moon, a series of activities developed specifically for use in libraries.(View Less)

The 9-session NASA Family Science Night program emables middle school children and their families to discover the wide variety of science, technology, engineering, and mathematics being performed at NASA and in everyday life. Family Science Night...(View More) programs explore various themes on the Sun, the Moon, the Stars, and the Universe through fun, hands-on activities, including at-home experiments. Instructions for obtaining the facilitator's guide are available on the Family Science Night site.(View Less)

This is a web site which explores the desire shared by past civilizations and today's society to observe and study the Sun. Learners can access two interactive modules, which include satellite images, aerial photographs, panoramic pictures,...(View More) time-lapse videos and other multimedia. Each module is focused on a different ancient culture: Maya in the Yucatan and Native Americans in Chaco Canyon.(View Less)

This is an activity about the shape of the Earth’s orbit. Learners will first use elements of the orbit of Earth and Pluto and an apparatus using string, a pencil, and pushpins to accurately draw an ellipse, showing the nearly circular shape of...(View More) the orbits of Earth and Pluto. They then measure real images of the Sun in each season, determining the apparent size of the Sun to see if it changes throughout the year. By determining the apparent size of each Sun image and by seeing the shape of Earth's orbit, learners will confront the misconception that seasons are caused by changing distance of the Earth from the Sun. Finally, learners reflect on the results of the Sun-Earth Survey, which is Activity 2 in this set. This is Activity 4 in the Great Explorations in Math and Science (GEMS) guide titled Real Reasons for Seasons: Sun-Earth Connections. The resource guide is available for purchase from the Lawrence Hall of Science. This activity recommends use of an overhead projector.(View Less)
